Abstract
The utility model relates to a thread-type lifting check valve which consists of a valve body, a valve seat, a valve clack and a bonnet, and is characterized in that the valve is in threaded connected with a pipe device. The utility model solves the problems existing in the current designed and produced lifting check valves which are usually connected with the pipe device in a welding way, and provides a liquid and gas flow control valve which has the advantages of convenient disassembling and convenient maintenance in long-term use. The thread-type lifting check valve can be widely used in the field of flow control of liquid and gas pipe devices.
Description
Technical field:
The utility model relates to the flow control field of fluid line, specifically a kind of flow control valve of adjutage duct device liquid.
Background technique:
Its connection pattern of valve that design production is gone up by present society is that weld seam connects, and its shortcoming is that leakage phenomenon appears in long-term use easily.
Summary of the invention:
The utility model connects the long-term problem that is prone to leakage phenomenon of using for solving the common valve weld seam, invents the valve that a kind of thread type connects.
The technical solution of the utility model is, a kind of thread type lift check valve comprises valve body, valve seat, flap, valve gap, outside it is special is, valve body adopts with pipeline and is threaded.
Vertical column flap is housed in valve body, and the lower end of flap places on the valve seat, and horizontal media outlet is left at the middle part of flap, leaves the medium import below the valve seat, and the lower end of flap becomes the conehead shape, and valve body is connected with the valve gap bolt.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, and it connects pattern for being threaded, and uses assurance leakage phenomenon not occur for a long time.
Description of drawings
Fig. 1 is the structural front view of model utility, and the accompanying drawing that makes an abstract.
Valve body, 2, valve seat, 3, flap, 4, valve gap in the drawings, 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, further specify this enforcement is novel.
As shown in FIG., vertical column flap 3 is housed in valve body 1, the lower end of flap 3 places on the valve seat 2, and horizontal media outlet is left at the middle part of flap 3, leaves the medium import below the valve seat 2, and the lower end of flap 3 becomes the conehead shape, valve body 1 and valve gap 4 bolted on connections.
Can realize that a kind of long-term use is not easy to produce the liquid flow control valve door of leakage phenomenon.
